What a load of bullshit you all talk. Jason wasn't upstaged by any member of the band, in fact I always considered him number two to james.

As for his reasons for leaving, if you think Metallica are only in it for the money, then he wouldn't have left would he! He would have frikkin well stayed and made shitloads more! His reasons are quite simple. Go to Metallica.com or MTV.com and read about it.
